Harry Anderson's work on the magic square is inspired. His booklet "Squaresville" not only gives you a unique presentation, it renders a wonderful history and philosophy regarding this effect.
I recently presented my own magic square at the Magic Castle and Cal Magic as part of the new performance style I call "Metaphysics" (the OCD act). I wanted to present an effect that involved pattern recognition. I talk about my love for astronomy and my ability at very early age to form the constellations 3D in mind, to form spatial relationships. I use the square to demonstrate this ability.
I really do have OCD and I became an astronomer at age 5 so the "backstory" is legit. The magic square can be a performance platform for your personality. Harry's routine certainly proves that.
Jim Steinmeyer presents a wonderful idea, a Sudoku magic square, in his book "Techniques and Understanding." A square update, brilliant.
If you want to look like a math wiz, google John von Neumann, game theory, prime numbers, fibernacci sequence, Pi, Phi, Kieth numbers and just for fun 47 and 42. It will give you a background on just how cool math can be and make your square all the more entertaining. In showbiz all things are good things except boring things.
